| Abstract | The versatile enantiopure cis-dihydrodiol metabolite 1, formed by bacterial metabolism of iodobenzene, has been used for the synthesis of the pyranose carbasugars (pseudosugars) carba-β-D-altropyranose 2, carba-α-L-galactopyranose 3, carba-β-D-idopyranose 4 and carba-β-L-glucopyranose 5. Substitution of the iodine atom by a carbomethoxy group, stereoselective catalytic hydrogenation of an α,β-unsaturated ester, and regioselective inversion of one or two allylic chiral centres are the key steps used in the synthesis of carbasugars 2-5. The relative and absolute configurations of compounds 2-5 were established by a combination of stereochemical correlation, X-ray crystallography and H-1-NMR spectroscopy. |
